Breve análisis del portátil HP EliteBook 820 G4 (7500U, Full HD)

Name: HP EliteBook 820 G4 Z2V72ET
Brand: HP

Con aguante. El último EliteBook de 12.5 pulgadas viene con procesador Kaby Lake asegurando con ello una mayor duración de batería. También nos han gustado otras características: pantalla IPS, SSD NVMe , 16 GB de RAM y modem LTE. Sin embargo el dispositivo tiene también algunos puntos débiles.

Parpadeo de Pantalla / PWM (Pulse-Width Modulation)

ℹ

Para atenuar el brillo de pantalla algunos portátiles están encendiendo y apagando la retroiluminación muy rápidamente. Esto se hace a una frecuencia que no debiera detectarse a simple vista. Si la frecuencia es demasiado lenta, la gente sensible podría experimentar problemas visuales, dolores de cabeza e incluso ver parpadeos.

Parpadeo de Pantalla / PWM no detectado

Comparación: 53 % de todos los dispositivos testados no usaron PWM para atenuar el display. Si se usó, medimos una media de 8743 (mínimo: 5 - máxmo: 343500) Hz.

Tiempos de respuesta del display

ℹ

Los tiempos de respuesta del display muestran lo rápido que puede cambiar la pantalla de un color al siguiente. Tiempos lentos de respuesta pueden llevar a imágenes persistentes alrededor de objetos en movimiento o a displays borrosos. Particularmente los aficionados a los juegos 3D frenéticos deberían usar una pantalla con tiempos de respuesta rápidos.

↔ Tiempo de respuesta de Negro a Blanco
26 ms ... subida ↗ y bajada ↘ combinada	↗ 7 ms subida
26 ms ... subida ↗ y bajada ↘ combinada	↘ 19 ms bajada
La pantalla mostró tiempos de respuesta relativamente lentos en nuestros tests pero podría ser demasiado lenta para los jugones. En comparación, todos los dispositivos de prueba van de ##min### (mínimo) a 240 (máximo) ms. » 59 % de todos los dispositivos son mejores. Eso quiere decir que el tiempo de respuesta es peor que la media (21 ms) de todos los dispositivos testados.

35 ms ... subida ↗ y bajada ↘ combinada	↘ 19 ms bajada
La pantalla mostró tiempos de respuesta lentos en nuestros tests y podría ser demasiado lenta para los jugones. En comparación, todos los dispositivos de prueba van de ##min### (mínimo) a 636 (máximo) ms. » 44 % de todos los dispositivos son mejores. Eso quiere decir que el tiempo de respuesta es similar al dispositivo testado medio (32.9 ms).

Análisis: HP EliteBook 820 G4 Z2V72ET. Modelo de prueba cedido por Notebooksbilliger.de

Incluso aunque el HP EliteBook 820 G4 sea solo una actualización Kaby Lake, podría resultar interesante para los poseedores del predecesor. Sin embargo, esto no es solo por el mayor rendimiento de Kaby Lake ante Skylake.

Una duración de batería significativamente mayor hace (aún más) atractivo este ordenador.

Independientemente de la carga de trabajo, el ordenador se mantiene en buena temperatura y funciona de forma silenciosa la mayor parte del tiempo. Esto último es cierto mientras que el ventilador no funcione o lo haga a baja velocidad. De otra forma se escucha un ligero silbido. Esto no debería ocurrir en dispositivos de este precio; más aún después de que esto fuera ya criticado en su predecesor.

El rápido NVMe-SSD asegura una buena respuesta del sistema. Es posible reemplazar el SSD. Esto requiere extraer la parte inferior del portátil - lo que no requiere mucho esfuerzo. El teclado y la carcasa no han cambiado: HP ofrece la calidad habitual.

Apenas podemos decir cosas buenas de las pantallas de los portátiles de negocios de HP. Sin embargo esta vez las cosas son distintas: HP ha incluido un panel IPS brillante, con contraste y buenos ángulos de visualización. Hasta los colores son muy decentes sin realizar ninguna calibración.
